IMPROVEMENT IN BUTTONS.

Specification forming part of Letters Patent No. 202,684, dated April23, 1878; application filed October 2, 1877.

To all whom it may concern.-

Be it known that we, WILLIAM Wnsr and WILLIAM F. SPITTLE, both ofBirmingham,

in the county of Warwick, in England, have invented certain new anduseful Improvements in Dress-Fastenin gs, Sleeve-Links, &c.; and we dohereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it .appertains to make and use the same, reference being had tothe accompanying drawings, and to letters of reference marked thereon,which form apart of this specification, in which similar lettersindicate similar parts.

The object of our invention is to produce dress-fastenin gs or othersimilar articles which may be readily and securely attached or detachedwithout passing either of the main parts of the fastenings through thehole in the garment.

In the construction of fastenings which contain our improvements onepart is made hollow, or, as may be generally preferable, by forming asmall box or case thereon, in which is fitted a spring-catcharrangement, or equivalent, for the purpose hereinafter described. Inthe center of one part of the fastening is the shank or solid pin,projecting through the center of hollow plate or box. Through the endsof the hollow plate, box, or case project the ends of the pushers, eachof said pushers being formed somewhat like a crescent at its in wardextremity, to hook against the connecting pin or shank, and each isprovided with projections, which hold the spiral springs which press thepushers against the shank. Further, the pushers are so constructed thatthey do not pass one over the other, both working on the same plane. Theother part of the fastening has'a hollow pin or shank, with collarroundthe outer edge, at the top part, wherein the solid pin hereinbeforementioned fits when the spring-catches secure it in its place, and holdsthe two parts of the fastener firmly together. By pressing the ends ofthe springcatches the hollow pin of the fastener will be released, andthe two parts can be separated and removed from the person, if desired.

The drawings accompanying these presents show the details of anarrangement for carrying out our said invention.

Figure 1 is a side view of our improved device. parts detached. Fig. 3is a plan view of the under side of the upper part of the fastening.Fig. 4 represents, in perspective, the upper part inverted. Fig. 5represents the pushers in plan view. Fig. 6 is a plan of the under sideof the upper part, showing two springs used with the pushers. Fig. 7represents the upper part inverted, the box containing the pushers beingpartially removed to show the pushers. Fig. Sis a vertical section ofthe fastening, taken through the center. Figs. 9 and 10 represent plansof plates or blanks used in constructing the main portion of thefastening. Fig. 11 shows, in side view, the central pin attached to aplate. Fig. 12 represents, in plan, the main plates forming the part A,with the pin. Fig. 13 is a side elevation of the main part A, showingslots in the box and guides for the pushers.

In the drawing, A designates the upper or main portion of the fastening,and B the lower part, the latter being formed of a disk of metal,similar to those used in ordinary sleeve-links, and having fixed to itat the center a tube, 6, with a projecting ring or collar, f, around theend of it. Under the upper part A of the fastener, the face of which canbe made of some ornamental pattern, we attach the box or case b,inclosing the bolts or pushers a and the springs 01. This box or case ispreferably secured in position to the plate formingthe under side of themain part A by means of lugs or ears passed through slots 1' in saidplate, and afterward clinched. In the center of the box I) there is around aperture, 8, through the center of which projects a pin, g, ofsuitable size and length to go into the tube e, which projects from thecenter of the lower part B of the fastener, as shown. Within the box bare the spring catches or pushers a, (see Fig. 5,) each of said pushersbeing provided with projections 10. and n, which hold the springs 41.The parts m of the pushers may protrude across the hole 8 up to the pin9, but so that when pressure is applied, either by the handles a of thepushers or by the introduction of the collar f of the tube e, theseparts m are pushed back on the springs d.

The hole s in the box or case is made of a Fig. 2 represents the buttonwith the suitable size to receive the collar f of the tube e, fixed tothe lower piece B, so that when said tube is pushed over the pin 9 ofthe upper part A it enters the hole 8 in the box b, and, a slightpressure being used on either part of the fastener, it forces back thecrescent-shaped ends m until the collar f passes beyond them, when thesprings force the parts m to close against the tube 6, which, by meansof the collar, is held fast.

It will be observed, from the form and construction of the pushers a,and from their relative positions, that the inward movement of each ofthem is properly limited.

To disengage the two parts in order to detach them from the garment, itis only necessary to use a slight pressure on the handles a, whichreleases the tube 6, and the parts A and B are readily separated.

In Fig. 7 is shown a plan of the inner side of the main part A of thefastening. The box b is shown partly in section, and two springs, 07,with two pushers, a, are employed. The relative positions of the springsd and their action on the bolts or pushers a will be readily understoodfrom Fig. 7.

As the action of each spring is the same as thatof the other, one ofthem may be dispensed with, as shown in Figs. 3 and 4, provided the oneretained be made of sufficient strength,

and the two pushers may be actuated by a single spring.

In order more effectually to guide the pushers a in their motion, theymay be provided with projections or ears h on their outer edges, whichwork in slots iin the sides of the box b. (See Figs. 7 and 13.)

Having described our invention, we claim and desire to secure by LettersPatent of the United States- 1. The pushers a,withtheirinnerendsformedto close against the central part, which connects the parts A and B,said pushers being provided with projections 'n and n, to hold thespiral springs 01, substantially as and for the purposes described.

2. In combination with the box b, the pushers a, each being providedwith a projection, h, to extend into a slot, i, in said box b, as setforth.

In testimony that we claim the foregoing as our own we affix oursignatures in presence of two witnesses.
